Nobody likes being camped. You usually have more than one spawn point , just re-spawn somewhere else. If your down to your last spawn ( which would be your base), there really isn't much the other team can do, they have to get the core. Besides if someone is camping a spawn point then leave them be , you will know where they are, not helping there team build nodes.
